RETROFITTING EQUIPMENT FOR A SHOOTING ARM AND METHOD FOR RETROFITTING A SHOOTING Weapon

The invention relates to a Umrüstbausatz for a firearm with a handle and a discharge opening having a locked by a movable barrel closure.

Moreover, the invention relates to a use of such Umrüstbausatzes.

Further, the invention relates to a method for converting a firearm with a handle and a discharge opening having a locked by a movable barrel closure.

Finally, the invention also relates to a method for operating a firearm with a handle and a discharge opening having a locked by a movable barrel closure, wherein the closure is moved to a shot firing backwards.

Firearms, especially self-loading pistols, usually have a closure, which closes a barrel when triggering a shot on the back. After a shot firing usually opens the shutter automatically, whereby a cartridge case can be removed from a chamber. To prevent injury, the shutter opens only when a gas pressure has dropped to a safe level. A correspondingly timely opening of the closure can be achieved on the one hand by an unlocked closure, which has a defined mass, so that due to inertia, a backward movement is introduced slowly enough. On the other hand, locked closure systems have become known, wherein the closure is connected to the barrel during the firing of the shot by means of solid locking elements. As a result, a lower weight of the firearm can be achieved compared to an unlocked closure.

In a Browning system, which is often used for pistols, the shutter is connected at shot firing by a locking comb with a movable barrel. After firing the shot, the cap and barrel are moved backward by the gas pressure relative to the handle of the gun. In this case, the barrel executes a tilting movement defined by a control cam in the grip piece backwards and downwards, while the closure is moved linearly to the rear. The movement of the barrel and the shutter in different directions separates the barrel from the cap while it is moving, unlocking the cap. Subsequently, an ejection opening between barrel and shutter is released. Tilting the barrel back and down also causes a cartridge case in a cartridge chamber of the barrel to be accelerated back and down. As a result, the cartridge shell bounces on a cartridge ejector, which is usually arranged below a barrel axis or in a rear part of the grip piece and underneath the cartridge chamber. In a subsequent rebound from the cartridge ejector, the cartridge case is thrown out of the firearm through the ejection port.

After the closure has arrived at a rear dead center, this is moved by a biased in the rearward movement of the closing spring back to forward, with a cartridge slipping out of a magazine is inserted through a push bottom of the closure and a Zuführrampe into the chamber. It also takes the barrel forward to a starting position so that the gun is locked again and ready to fire. Often, a cartridge extractor is provided in the closure to reliably guide the cartridge case on the shock bottom and take off.

Such a Browning system having firearms are light and resistant to dirt, which is why such pistols, such as a so-called Glock pistol, often 1/23

Merreöiise-ts pitesSenses AT513 605B1 2014-06-15 such as police units. The disadvantage, however, that these guns have only a low intrinsic precision and short ranges of about 50 m due to the movable or tipping, short barrel. Although a self-precision can be improved when using a longer and / or non-tilting alternate barrel, replacement of the short-barreled, short barrel with such a barrel is not compatible with the Browning system.

A replacement of the tipping, short barrel by a locking the interlock locking alternating leads in particular to the fact that an opening of the closure is not done in time or is not possible and a cartridge case can not be ejected. Using a change-over barrel that does not lock the breech opens the breech too early, resulting in a high risk of injury.

This is where the invention begins. The object of the invention is to provide a Umrüstbausatz of the type mentioned, with which a timely opening of the closure is then ensured if a lock not interlocking lock is used to increase the precision of the firearm.

A second object of the invention is to provide a use of such Umrüstbausatzes.

Further, it is an object of the invention to provide a method of the type mentioned, with which a firearm is easily convertible, so that a timely opening of the closure is ensured after a shot firing, if not to increase the precision of the firearm a closure locking interchangeable barrel is used.

Moreover, it is an object of the invention to provide a method for operating a firearm of the type mentioned, with improved precision of the firearm is achieved and timely opening of the closure is ensured.

The first object is achieved by a Umrüstbausatz of the aforementioned type, which comprises a lock releasably connectable to the closure for a use of a non-interlocking closure, wherein the jacket has a defined mass for the predetermined movement of the closure after a Shot triggering has.

By connected to the closure coat to be accelerated after a firing shot mass is increased, whereby then acting as a grounding closure opens in time, even if a lock is not interlocking barrel used. A mass of the shell therefore results from a mass of the closure, an inserted ammunition and a desired delay time between a shot triggering and an ejection of the cartridge case. Thus, a firearm with movable, short barrel and low precision can be easily and reversibly converted to a firearm with high precision or high intrinsic precision.

Because such a coat can be easily formed, for example, as a steel part, the Umrüstbausatz can be produced at low cost and easy to transport.

For a particularly good connection between the jacket and closure, it is advantageous if the jacket is formed enveloping the closure. The jacket preferably encloses the closure in a retrofitted firearm on five sides, wherein the jacket has laterally a discharge opening corresponding to an ejection opening of the closure and at a front side a usually round opening for the barrel. When converting the coat is usually placed over the closure or put on this, so that a simple producible, positive connection is given.

It is advantageous if a cocking slide is arranged on the jacket in order to be able to repeat the closure with mounted jacket easily. The cocking slide can directly, for example by a bolt usually releasably connected to the jacket, or indirectly 2/23

AT513 605B1 2014-06-15 be formed by a movably mounted in a housing part. In such an indirect embodiment, only a contact surface for the cocking slide is provided in the shell, in order to achieve a simple construction.

It is advantageous if the jacket has on a front side a recess for a spring guide rod, so that a good mobility of the closure together with the jacket is given to the handle and connected to the handle spring guide rod is favorable.

It can also be provided that a contact surface for the closing spring is provided directly on a front side of the shell, in particular when the jacket is designed for a firearm, in which a so-called bushing is not mandatory, for example, a so-called Colt-M 1911 pistol.

In many pistols such as the Glock pistol, it is possible to allow by attaching a continuous firing device in the jacket a continuous fire operation. A lever for switching between a continuous fire mode and a single fire mode may be positioned in the shell or in a housing connected to the gun for ease of construction. It is favorable if a jacket for a pistol with a continuous fire device arranged in the closure, for example a Glock pistol model 18, has a recess through which a switching lever or switching button of the continuous firing device can be operated in order to be able to operate it easily.

Advantageously, the jacket has a fixing recess for fixing on the closure by a projecting from the ejection opening cartridge extractor. As a result, a very stable, positive connection between shell and closure can be formed. Especially with Glock pistols, the cartridge extractor protrudes from the ejection opening of the shutter when a cartridge is loaded, so that a fixation can be easily ensured by a corresponding corresponding recess in the jacket. In addition, the coat is fixed to the closure by the replacement barrel inserted in the converted firearm, and guided in a movement to the rear of the replacement barrel.

To ensure a function of a carriage catch, it is advantageous if the mantle has a catch catch of the closure expanding catch catch to increase a contact surface with the carriage catch. As a result, an excessive pressing of a surface serving as a catch on the closure can easily be avoided.

It is advantageous that the Umrüstbausatz includes a connectable to the firearm reset means by which a force in the closure of a cartridge case a force in the direction of a arranged in the firearm cartridge ejector is exercisable. With such a restoring device, a movement of the cartridge case to the cartridge ejector is achieved during a movement of the closure together with the cartridge case to the rear after a shot triggering, usually downwards. Characterized a contact of the cartridge case with the cartridge ejector is ensured even if a rigidly connected to the handle barrel is used and the cartridge ejector is located below the barrel axis or below the cartridge chamber, as is common in the Glock pistol. With such a restoring device, a reliable ejection of a cartridge case in such a firearm can thus be achieved even if a rigid alternating barrel is used.

In firearms, in which the cartridge ejector is not located below the barrel axis or below the cartridge chamber, such a return device is not required. Such firearms have, for example, a groove in a shockbore, through which a central cartridge ejector projects, onto which the cartridge shell bounces after a shot being fired and is thus ejected.

A structurally simple and robust construction is achieved when the restoring device is arranged in the jacket, preferably at one corresponding to the ejection opening 3/23

(sterrec piesiasfit AT513 605B1 2014-06-15 the position.

Conveniently, the return device is designed as a flat spring. This ensures a very cost-effective manufacturability. When the flat spring is positioned in the jacket, a connection of the flat spring with the jacket usually takes place in a form-fitting manner through a shaping groove, for example a dovetail groove. However, the flat spring normally disposed between shell and closure may also be connected to an attachment recess at an additional bend by a connecting means such as a screw or bolt to the shell.

It is advantageous if the leaf spring is arranged on a corresponding to a groove for a running approach in the closure position in the jacket. As a result, the leaf spring can protrude through this groove in the firearm, whereby a conversion with very little effort is possible.

When feeding a cartridge from the magazine from below, the leaf spring is pushed upwards, with an approximately vertical force is exerted downward on the cartridge. A lifting of the shell from the closure due to this vertical force is ensured by the barrel, which fixes the coat on the closure, so that a function of the firearm is guaranteed.

If the cartridge is pulled out by the after a shot firing under the action of the gas pressure rearwardly moving shutter, the flat spring continues to push the cartridge case down so that it is moved relative to the barrel axis down to the cartridge ejector and as in an operation with abkippendem run bouncing on the cartridge ejector. At the cartridge ejector, the cartridge shell bounces off and is ejected through the ejection port.

Advantageously, a rigidly connectable to the handle changeable barrel is provided, which is preferably inserted from the front into the closure. As a result, the intrinsic precision of the firearm is increased because the barrel does not tip over after the shot has been fired, whereby a position of the barrel to a target device always remains the same. In general, the removable barrel is detachably connectable to the handle so that the firearm can be easily and reversibly converted from a Browning system with tipping barrel to a firearm with a rigid barrel. In order to further increase the precision, in particular the self-precision, of the firearm, it has been proven that the replacement barrel is designed to be longer than the movable or tipping barrel usually located in the firearm.

For a simple assembly of the removable barrel is preferably designed such that it can be inserted from the front through the opening in the closure. Normally, the alternating barrel, which is advantageously substantially rotationally symmetrical, as a rule cylindrical, has different diameters over a run length and shoulders at a transition between the different diameters, so that a defined stop of the change barrel is provided at a mounting position.

The removable barrel can be indirectly connected directly or indirectly via an intermediate piece with the handle, usually by screws and / or clamps. A simple and robust construction results when a releasably connectable to the handle housing is provided, through which the interchangeable barrel is indirectly connected to the handle, preferably non-positively. The housing may also be designed for a positive and non-positive connection in order to achieve a high accuracy of fit with the handle. A connection between the housing and the removable barrel can be made, for example, by a threaded part arranged in the housing, to which the alternating barrel can be fixed by means of a union nut or another fixing means. It can be provided at the interchangeable barrel, in particular on a shoulder of the interchangeable barrel, a groove or flat and on the threaded portion a corresponding elevation in order to achieve a stable, positive and non-positive connection. This also allows easy insertion of different barrels with different run lengths. 4.23

A very stable connection between the housing and the handle results in a structurally simple manner when two half-shells are provided, which have a negative mold of a part of the handle and on the one hand with the handle and on the other hand with the housing are connectable. As a result, on the one hand, a large contact surface is achieved with little pressure between the half shells and the grip piece, so that wear is reduced when the half shells are positively connected to the grip piece. On the other hand, a connection to the housing can be made easily and quickly, for example, by a shaft connecting the housing and the half-shells, which is preferably fixed by means of a quick release lever and a Wellenfixiermutter. A power transmission between the housing and the half shells takes place over a large area and with low surface pressure, in particular when a shaft with a large diameter is used. In order to minimize a load on the handle, an insertable support in the housing may be provided on a rear side of the handle, through which a stable connection between the handle and the housing is achieved. For firearms with a tap, such as the Colt-M 1911 pistol, it is favorable if no corresponding support is provided in order to achieve good operability of the cock. The housing may be similar to a shaft system available under the trade KPOS system.

By a shaft mounted in the housing with a semi-circular cross-section, a connection between the half-shells and the housing can be made with a high accuracy of fit. In addition, this achieves a simple and fast fixability. For this purpose, the shaft is inserted through a guide with a cross section corresponding to a narrow side of the semicircular cross section in the half shells and rotated at a Wellenfixierausnehmung with a cross section corresponding to a broad side of the semicircular cross section through 180 °, whereby a positive connection is made. In contrast to the KPOS system, a fixation is effected by pivoting the quick release lever through 180 °, so that the quick release lever can be pivoted into the recess after being fixed and a position of the quick release lever, in contrast to the KPOS system, is irrelevant. This improves handling.

In addition, a so-called Picatinny rail can be provided on the half shells so that more accessories with the handle can be connected via the half shells.

Typically, a Zuführrampe part of the barrel and cohesively connected to a rear end of the barrel with this, are guided over which from the magazine nachrutschende cartridges in the cartridge chamber. In the case of a removable barrel which can be introduced from the front into the closure, this is generally not possible due to a size of the opening in the closure. In order nevertheless to ensure a supply of cartridges, it is advantageous to provide a feed ramp which can be introduced through the ejection opening into the firearm. A connection of this separate feed ramp with the handle is usually done form-fitting, preferably on a control cam or a chain link axis, which defines a Abkippbewegung at a tipping barrel, whereby the feed ramp is fixed in the longitudinal direction. It is advantageous if the feed ramp is finally fixed by introducing the removable barrel, which usually protrudes in the installed state up to the feed ramp. For example, this can be done by a positive fixation of the feed ramp in the control cam, wherein the feed ramp is fixed between the control cam and removable barrel.

The precision of the firearm can be easily further improved if a connectable with the firearm stop shaft is provided. As a result, the weapon can be easily taken in a shoulder stop, whereby an improved goals is possible. In general, the stop shaft with the firearm is indirectly connected by the housing. Usually, a hinged connection between the housing and stop shaft is provided so that the housing on the one hand stowed in a small space and on the other hand, the stop shaft can be quickly folded into a firing position when needed.

Timely closure of the closure and quick loading of a converted firearm are easily ensured if a replacement closing spring for return 5/23

S &sub1; is provided after the shot firing which has a higher rigidity than a closing spring inserted in the firearm. Due to the increased rigidity, despite the increased by the shell, to be accelerated in a loading movement masses rapid charging. The exchange closing spring can be used instead of the original closing spring or be an additional spring, which is connected in parallel to the originally used closing spring. For example, an additional closing spring on the one hand in a rear portion of the housing and on the other hand with the jacket, preferably on an upper side, be connected so that an overall spring stiffness is increased even using the original closing spring. A particularly simple retooling is possible if a stiffer closing spring is used instead of an original closing spring, for example, can be used to retrofit a gun Glock 19 a closing spring a gun Glock 17 type. A spring force results depending on the selected length of the replacement barrel and mass of the shell. So even with a lighter coat a stronger exchange closing spring may be required. However, it can in principle, depending on the vote of run length and mass of the shell, and the original closing spring can be used.

It is advantageous if a firearm with a handle, a discharge opening having closure and a cartridge ejector is retrofitted with a Umrüstbausatz invention. This can be improved in a simple manner and at low cost, the precision of the firearm. Because retrofitting with the retrofit kit according to the invention is reversible, the firearm, for example, can be easily and quickly converted back to an original state with tipping and low weight after use for long ranges.

The second object is achieved in that an inventive Umrüstbausatz is used to convert a firearm with a movable barrel on a firearm with a rigid barrel. As a result, the intrinsic precision of a firearm is improved in a simple manner.

The further object is achieved in that a coat with the closure is releasably connected in a method of the type mentioned for converting a firearm for use of a lock not interlocking alternating barrel, wherein the jacket has a defined mass for the predetermined movement of the closure after a shot firing has. Because an additional weight for the closure is formed by the jacket, a timely opening of the closure is thus ensured in a simple manner even when using a rigid, non-locking lock the interchangeable barrel. A connection of the shell with the closure is usually carried out by a form-fitting closure by a coat enveloping the closure.

To ensure ejection of the cartridge case even with firearms with a positioned below a barrel axis cartridge ejector, a restoring means is suitably connected to the firearm through which a cartridge located in the cap a force approximately in the direction of a arranged in the firearm cartridge ejector is exercisable , Usually, this is a sheath-mounted flat spring.

A high range and improved precision can be easily achieved if the barrel is replaced by a removable barrel, which is rigidly connected to the handle.

For a simple conversion, it is advantageous if the removable barrel is inserted from the front into the closure. Furthermore, it is easily possible to use a change barrel that is longer in relation to an originally inserted barrel.

Conveniently, the firearm is preferably non-positively connected to a housing, which connects the removable running indirectly with the handle. As stated above, this is normally done via half-shells, which are connected to the handle frictionally and / or positively releasably. 6/23 Austrian! In order to ensure a supply of cartridges when using a change-over barrel, it is advantageous if a feed ramp is inserted through the ejection opening into the firearm and connected in a form-fitting manner to the grip piece.

The further object is achieved in that in a method of the type mentioned for operating a firearm, the lock non-interlocking removable barrel is used and the closure after the shot trigger due to a releasably connected to the closure shell with a defined mass only after opens a predetermined time. As a result, with a conventional firearm, a high range and simultaneously improved precision can be achieved. In addition, the firearm can easily be converted back to an original state with tipping barrel, since the jacket and the removable barrel are usually reversibly connected to the firearm. The predetermined time, after which the shutter opens, is usually that time within which a gas pressure in the alternating operation has dropped to an uncritical value.

Preferably, force is applied to a cartridge case in the direction of a cartridge ejector disposed in the firearm by means of a reset device connected to the firearm whereby the cartridge case impacts on the cartridge ejector as the shutter is moved rearward and ejected through the ejection port. This ensures a cartridge ejection even if a firearm is used with a arranged below the barrel axis cartridge ejector.

Further features, advantages and effects of the invention will become apparent from the embodiment illustrated below. Referring to the drawings, wherein: Figs. 1 and 2 Fig. 3 Fig. 4 through Fig. 8

Exploded views of a converted firearm; a plan view of a converted firearm;

Sectional views of a converted with a Umrüstbausatz invention firearm; 9 to 12 a detail of a converted firearm in different views.

Fig. 1 and 2 show a converted with a Umrüstbausatz invention firearm 1 in an exploded view. Shown is a retrofitted Glock gun, which typically has a dumping barrel that closes a closure 2 according to a Browning system.

In order to achieve an increased range and improved precision with the Glock pistol, instead of the original barrel in the converted firearm 1, a removable barrel 4 is used, which rigidly connected to a threaded portion 16 and a housing 19 with an original handle 7 of Glock pistol is connected. Since the interchangeable barrel 4 is not tilted or not movable and is designed without a locking comb corresponding to the closure 2, the interchangeable barrel 4 does not close the closure 2 even when a shot is fired.

A structurally simple construction of Umrüstbausatzes is achieved because in an inventively retrofitted firearm 1 of the original shutter 2 of the Glock pistol is used. In order to ensure a timely opening of this closure 2 despite the use of a non-interlocking lock 4 after a shot release, a jacket 3 enveloping the closure 2 is provided which has an inner contour corresponding to an outer contour of the closure 2. This is connected to increase a mass of the closure 2 releasably connected thereto.

To produce a connection between the closure 2 and the jacket 3, the jacket 3 is placed on the closure 2. On a front side of the shell 3 is a preferably round, 4 for changing clearance corresponding jacket opening 43 is provided, through which the interchangeable barrel 4 in the closure 2 insertable and with the firearm 1 is connectable. As a result, the mantle 3 is fixed on the breech 2, and a loosening also occurs in a movement of the Austrian; FohlenSawi AT513 605B1 2014-06-15

Final 2 relative to the handle 7 simply prevented. With an inserted cartridge 36, the shell 3 is further connected by a laterally pressed out to the outside cartridge extractor 27 with the shutter 2 at a Fixierausnehmung 28.

The interchangeable barrel 4 is connected to the handle 7 by a housing 19 by means of a threaded portion 16, wherein the threaded portion 16 is fixed in the housing 19 by fixing screws 18. With the threaded portion 16 of the interchangeable barrel 4 is connected by means of a union nut 17, as is common in other weapons, for example, in a so-called Uzi. For a secure, positive connection, a survey 35 is provided on the threaded portion 16, which corresponds to a flat 34 on a shoulder 33 of the interchangeable barrel 4. The cap nut 17 is fixed by a locking pin 31 and a Sicherungsstiftfixierschraube 32 in a closed state on the threaded portion 16.

A compound of the housing 19 with the handle 7 is on the one hand form-fitting manner by a corresponding shape of the handle 7 with an inner contour of the housing 19. On the other hand, a positive and non-positive connection between the housing 19 and handle 7 indirectly by two between the housing 19 and These each have a part of the handle 7 corresponding half-shell inner contour 44, which allows a large-area connection with the handle 7, so that a surface pressure and wear are minimized. A connection between the half-shells 11 and the housing 19 is realized by a shaft 12 mounted in bores 13 of the housing 12, which at least partially has a non-circular cross section, preferably a semicircular cross section. Correspondingly, a guide 41 and a Wellenfixierausnehmung 40 are provided in the half-shells 11, wherein the shaft 12 is feasible only with rotated in a certain position cross-section through the guide 41 to the Wellenfixierausnehmung 40. In the illustrated embodiment, a center of gravity of the shaft 12 must be turned down. At the Wellenfixierausnehmung 40, the shaft 12 is rotated by 180 °, so that a stable connection at a contact surface between the shaft 12 and Wellenfixierausnehmung 40 and between the Halbschaleninnenkon-tures 44 and the handle 7 results. In order to fix the shaft 12 in this position, a quick-release lever 10 is provided at one end of the shaft 12 and at a further end of the shaft 12 a Wellenfixiermutter 39, so that the shaft 12 can be fixed non-positively on the housing 19.

The interchangeable barrel 4 is formed substantially rotationally symmetrical for insertion from the front into the closure 2 and, in contrast to an originally inserted barrel, has no end feed ramp 9 for a cartridge feed, for which reason the conversion kit comprises a separate feed ramp 9, which by the Ejection opening 26 is inserted into the firearm 1.

In a Glock pistol, a cartridge ejector 29 is usually arranged below a running axis 37 or below a cartridge chamber 8. Due to the original tilting barrel, a cartridge shell is accelerated downwards in the direction of the cartridge ejector 29 after a firing of the shot and is ejected in a rebounding manner. In order to achieve a safe ejection of the cartridge case in spite of the used, rigidly connected to the handle 7 change cycle 4, a connected to the shell 3 flat spring 23 is provided which pushes the cartridge case down so that a cartridge case upon a return movement of the closure 2 bounces upon a shot firing on the cartridge ejector 29 and then ejected through the ejection opening 26. The flat spring 23 is bent, attached to the end of the shell 3 in a fastening recess 38 and executed with a corresponding to a groove 24 of the closure 2 dimension. As a result, the flat spring 23 can be inserted through the groove 24 of the closure 2 through the closure 2 into the firearm 1.

In order to bring the closure 2 and the jacket 3 back into a front position or a loading position after a firing from a rear end position, an exchange closing spring 5 is provided, which is replaced by a spring guide rod 6 of the original 8/23 asterreidBsd! Pitwiarot AT513 605B1 2014-06-15

Glock pistol is guided. Depending on the vote, the exchange closing spring 5 can have a higher rigidity than a closing spring normally used in the firearm 1, in order to initiate a movement forward with corresponding acceleration despite increased masses to be accelerated and to enable rapid loading.

Further, a catch catch of the closure 2 extending catch catch is provided on the jacket 3, to increase a contact surface and to avoid excessively high pressures on the catch catch of the closure 2.

In the illustrated embodiment, an original magazine 15 of the Glock pistol is used. Alternatively, a larger or longer magazine 15 can be used to increase a cartridge capacity.

On an upper side of the housing 19, a Picatinny rail 30 is provided, on which further accessories can be detachably mounted, for example a target device.

Further, corresponding rails for mounting additional accessories can also be arranged laterally on the housing 19. A corresponding Picatinny rail 30 is advantageously also arranged on an underside of the Flalbschalen 11, so that the Umrüstbausatz is expandable in a simple manner.

The jacket 3 has a cocking slide opening 22, in which a cocking slide 20 is detachably fixed, so that the converted firearm 1 can also be easily loaded manually. By a provided in the housing 19, elongated Spannschieberausnehmung 21 of the jacket 3 and the shutter 2 moving clamping slide 20 can be moved relative to the housing 19 even when the housing 19 is mounted. When retooling the cocking slide 20 is inserted through the Spannschieberausnehmung 21 of the housing 19 in the cocking slide opening 22 of the shell 3, after the jacket 3 and the housing 19 are mounted.

FIG. 3 shows a firearm 1 converted with a conversion kit according to the invention in a plan view. In this case, the housing 19 is connected to the handle 7 by the shaft 12, which is fixed by means of the quick release lever 10 on the one hand and by means of a Wellenfixiermutter 39 on the other hand on the housing 19. Furthermore, the change-over shaft 4 connected to the housing 19 by the union nut 17 and the cocking slide 20 located in a rear end position, by means of which the firearm 1 can be loaded manually, are shown.

Fig. 4 shows a section through a firearm 1 along the line IV-IV in Fig. 3. It can be seen that the shutter 2 and the shell 3 are in a rear end position, wherein the exchange closing spring 5 is compressed. During a forward movement of the shutter 2, the cartridge 36 is guided by relaxing the exchange closing spring 5 via the feed ramp 9 in the chamber 8, wherein the forward movement of the shutter 2 is transmitted through a shock pad 45 to the cartridge 36.

At the same time, the cartridge 36 is pushed in the forward movement by the feed ramp 9 upwards, wherein the flat spring 23 is pressed elastically upwards. The feed ramp 9 is arranged as shown on a control cam 42 in the handle 7 and is fixed by the rigidly connected to the handle 7 changeable barrel 4.

Further, it can be seen that the housing 19 is connected to the half shells 11 through the shaft 12, wherein the half-round cross-section of the shaft 12 is rotated in the Wellenfixierausnehmung 40 upwards to produce a positive connection.

As shown, the barrel is connected to the handle 7 through the union nut 17 and the threaded portion 16, wherein the threaded portion 16 is fixed in the housing 19 by fixing screws 18. A connection between the union nut 17 and the threaded portion 16 is ensured by a locking pin 31 and a Sicherungsstiftfixierschraube 32.

Fig. 5 shows a section through a firearm 1 along the line V-V in Fig. 4. It can be seen, the fixing of the housing 19 to the half-shells 11 by the shaft 12 by means of 9/23

Sförreicfsäcses AT513 605B1 2014-06-15 of the semi-circular cross-section of the shaft 12 in a central area. A resulting from the half-round cross-section, in an axial section approximately rectangular wave recess 14 allows an import of the shaft 12 in the guide 41 of the half-shells 11 when the shaft 12 is rotated relative to the position shown by 180 °. In the illustrated position, the shaft 12 is fixed by the quick release lever 10 and the shaft fixing nut 39.

Furthermore, it can be seen that the housing 19 on an upper side and the half-shells 11 on a lower side have a dovetail-like cross-section. With a corresponding profile in each case a Picatinny rail 30 is formed for receiving accessories.

Fig. 6 shows a section through a firearm 1 along the line Vl-Vl in Fig. 4. It can be seen that a cartridge 36 is positioned at an upper end of a schematically illustrated magazine 15. Further, a cartridge extractor 27 and the flat spring 23 are shown, which are elastically moved when loading the cartridge 36. In this case, the resiliently executed cartridge extractor 27 is moved to the side, wherein this engages in a fixing recess 28 of the shell 3 and thus fixes this form-fitting manner on the closure 2. The restoring device, which is in a relaxed position and is designed as a flat spring 23, is pushed up when the cartridge 36 is loaded, with a force being exerted on the cartridge 36 downwards. Further, the cartridge ejector 29 arranged below the barrel axis 37 is shown, from which a cartridge shell ricochets after a shot firing and is ejected through the ejection opening 26 formed in the cap 2 and in the shell 3.

FIG. 7 shows a firearm 1 according to FIG. 3, wherein the closure 2 and the casing 3 are moved from the rear end position back to a front end position and the replacement closing spring 5 is relaxed. In addition, there is a cartridge 36 in the chamber 8, so that the firearm 1 is loaded. The flat spring 23 is elastically deformed by the cartridge 36 and pushed upward, so this exerts a force on the cartridge 36 down.

FIG. 8 shows a section through a firearm 1 along the line VIII-VIII in FIG. 7.

As shown, the shell 3 is fixed in the illustrated position by the outwardly displaced cartridge extractor 27 on the closure 2, since the cartridge extractor 27 engages in the fixing recess 28 of the shell 3. As a result, a positive fixation of the shell 3 on the closure 2 is ensured.

9 to 12 show in various views a detail of a converted firearm 1, wherein a shell 3 including the closure 2 and flat spring 23 existing assembly is shown. FIG. 12 shows a section through the assembly along the line XII-XII in FIG. 11. It can be seen that the jacket 3 encloses the closure 2, so that a positive connection is provided. It can also be seen that the flat spring 23 fastened in the fastening recess 38 is arranged between the jacket 3 and the closure 2 and projects through the groove 24 into the firearm 1. In addition, the ejection opening 26 and the Fixierausnehmung 28 can be seen, in which the cartridge extractor 27 engages with loaded cartridge 36 to fix the jacket 3 on the closure 2. At a front end of the shell 3, the shell opening 43 is provided through which the removable barrel 4 is inserted into the firearm 1. Further, a recess 25 is provided for the spring guide rod 6 at a front end of the shell 3, to allow movement of the shell 3 after a firing shot to the rear. In a rear area, the jacket 3 has the cocking slide recess 21, in which the cocking slide 20 can be connected to the jacket 3, so that the firearm 1 can be manually loaded even when arranged in a housing 19.

For retooling a firearm 1 such as a Glock pistol, the magazine 15 and the shutter 2 are released from the firearm 1 and an original barrel and an original recoil spring are removed. Subsequently, the exchange closing spring 5 is fixed in the handle 7 and the shutter 2 is again connected to the handle 7, after which the feed ramp 9 by 10/23

The ejection opening 26 is inserted into the closure 2 and arranged on the control curve 42. In a next step, the jacket 3 is placed on the closure 2, after which the housing 19 is connected by the shaft 12 with the handle 7. Finally, the cocking slide 20 are fixed by the Spannschieberausnehmung 21 in the cocking slide opening 22 and the interchangeable barrel 4 rigidly connected via the connected to the firearm 1 housing 19 by the threaded portion 16 and the union nut 17 with the handle 7, whereby the Zuführrampe 9 on the control cam 42nd is fixed. Through the interchangeable barrel 4 and the shell 3 is fixed to the closure 2. Now the magazine 15 can be used again and the firearm 1 loaded.

With a conversion kit according to the invention a firearm 1 with low mass and short range such as a Glock pistol can be converted very easily changing a locking system and a run length to a carabiner system, which has an increased range of more than 100 m and a has improved intrinsic precision. A conversion can be done quickly and reversibly, so that a change from a state with a tipping barrel to a state with an extended, rigid alternating barrel 4 is easily possible. Because multiple parts of the original firearm 1 as the shutter 2 and the handle 7 can be used and the additional required for the Umrüstbausatz components, for example, by turning or milling, can be produced, a production of a corresponding Umrüstbausatzes with little effort is possible.

The manufacturing cost of a Umrüstbausatzes invention are only slightly above the cost of commercially available shaft systems, for example, under the trade KPOS (Fab Defense) or TRIARII (Hera Arms) are known, but with a Umrüstbausatz invention can in contrast to known shaft systems also a range and an intrinsic precision of a firearm 1 can be improved. 11/23
